Whereupon, whether driven by necessity, or on the suggestion of some wiser man among them and to escape anarchy, the people reverted to a monarchy, from which, step by step, in the manner and for the causes already assigned, they came round once more to license.

For this is the circle revolving within which all States are and have been governed; although in the same State the same forms of Government rarely repeat themselves, because hardly any State can have such vitality as to pass through such a cycle more than once, and still together.

For it may be expected that in some sea of disaster, when a State must always be wanting prudent counsels and in strength, it will become subject to some neighbouring and better-governed State; though assuming this not to happen, it might well pass for an indefinite period from one of these forms of government to another.
I say, then, that all these six forms of government are pernicious--the three good kinds, from their brief duration the three bad, from their inherent badness.

Wise legislators therefore, knowing these defects, and avoiding each of these forms in its simplicity, have made choice of a form which shares in the qualities of all the first three, and which they judge to be more stable and lasting than any of these separately.
For where we have a monarchy, an aristocracy, and a democracy existing together in the same city, each of the three serves as a check upon the other.
Among those who have earned special praise by devising a constitution of this nature, was Lycurgus, who so framed the laws of Sparta as to assign their proper functions to kings, nobles, and commons; and in this way established a government, which, to his great glory and to the peace and tranquility of his country, lasted for more than eight hundred years.
The contrary, however, happened in the case of Solon; who by the turn he gave to the institutions of Athens, created there a purely democratic government, of such brief duration, that I himself lived to witness the beginning of the despotism of Pisistratus.

And although, forty years later, the heirs of Pisistratus were driven out, and Athens recovered her freedom, nevertheless because she reverted to the same form government as had been established by Solon, she could maintain it for only a hundred years more; for though to preserve it, many ordinances were passed for repressing the ambition of the great and the turbulence of the people, against which Solon had not provided, still, since neither the monarchic nor the aristocratic element was given a place in her constitution, Athens, as compared with Sparta, had but a short life.
But let us now turn to Rome, which city, although she had no Lycurgus to give her from the first such a constitution as would preserve her long in freedom, through a series of accidents, caused by the contests between the commons and the senate, obtained by chance what the foresight of her founders failed to provide.
